If you tap one of the taillights the CHMSL will flash with that light. Tapping both will give you constant signal from light that isn't flashing. Requires diodes (or little magic box) on the taillight leads so not back-feeding each other.

Even with diodes the center light would flash if you initiate a turn signal without applying the brakes, or until you do apply the brakes. That’s why you need an electronic circuit to detect both lights on/both lights off to prevent the center light flash.
